Latest Patents

Yuzu Kato holds a patent for a method of manufacturing a high strength rail with good toughness. This method involves cooling a rail to the Ar.sub.3 transformation point or less after hot rolling. The cooled rail is then heated within the austenite temperature zone, ranging from the Ac.sub.3 transformation point to 950°C, followed by a controlled cooling process. The chemical composition of the rail includes 0.50 to 0.85 wt. % C, 0.50 to 1.50 wt. % Mn, 0.035 wt. % S or less, 0.10 to 1.00 wt. % Si, 0.035 wt. % P or less, and 0.050 wt. % Al or less, with the balance being iron and inevitable impurities. This innovative method has the potential to significantly improve the durability and performance of railway infrastructure.
